What the hell is Windows Phone Tango?

We’ve been hearing whispers of a little something called Windows Phone Tango over the past few weeks. Of course, the next big Windows Phone update is Mango, and after that we’re expecting WP8: Apollo.

So where the hell does Windows Phone Tango fit in?

An anonymous source tells Zdnet that Tango is “all about Nokia”, and is geared towards helping the Finns define an entry-level tier for Windows Phone 7. Also, it might be focused “largely or even exclusively on the Asian market.”

At the moment there’s very little choice in terms of Windows Phone 7 handsets, and they mostly sit in the 3.7in 1GHz area, or thereabouts. There aren’t any modest 3.2in 600MHz HTC Wildfire-style efforts.

Incidentally, all Windows Phone versions end with an ‘o’. The current release, NoDo, is thought to be a dig at Android (NoDonut), and Apollo may or may not be aimed at Apple.
